From b0a9e8f81fc45e6d3c9ddf290dabd7f4610f2939 Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Thu, 15 Jun 2023 06:53:10 -0700 Subject: [PATCH] perf stat,jevents: Introduce Default tags for the default mode Introduce a new metricgroup, Default, to tag all the metric groups which will be collected in the default mode. Add a new field, DefaultMetricgroupName, in the JSON file to indicate the real metric group name. It will be printed in the default output to replace the event names. There is nothing changed for the output format. On SPR, both TopdownL1 and TopdownL2 are displayed in the default output. On ARM, Intel ICL and later platforms (before SPR), only TopdownL1 is displayed in the default output.
